Rivers Available: 

As this is a fully customizable outfitter, thier area of operation is the waters of Northern Patagonia. If there is an area you are particularly interested in fishing let us know and we'll do our very best to meet your needs. The following is just a small portion of the available fisheries. 




A Classic Float on a legendary River. Known for it’s big Browns the Limay is famous for being one of the most epic multi-day float fishing in the world! The Limay River is one of the largest rivers in the region and flows for 236 miles from it’s headwaters at Nahuel Huapi Lake. Upon joining the Neuquen River it forms the famous Rio Negro. There are five reservoirs along the length of the river.

The Limay is one of the most mysterious rivers in all of Patagonia. It is the largest drainage basin in the region and flows for 236 miles from its origin in Nahuel Huapi Lake until it joins with the Neuquén River to form the Rio Negro. The Limay is interrupted in this 236-mile journey by five reservoirs and is a classic freestone river. From it’s source the Limay flows 30 miles before its first reservoir, it then flows immediately into two more reservoirs. Our fishing focuses on this 50-mile stretch, below the Pichi Picún Leufú Dam where the river becomes the Limay Medio (Middle Limay).The only tailwater in the region. It ends at Ezequiel Ramos Mejia Lake, the largest reservoir on the entire system. The Pichi Picun Leufu Dam stable release is responsible for one of the most productive trout habitats in the world. It is also a prime spawning run of several large minnow species that swim up stream annually. Lots and lots of food for big trout! Limited access to the upper 15 miles of the Limay Medio and virtually no access on the lower 35 miles means little pressure and you’ll truly enjoy being the only camp and probably the only fishermen on the river! Our outfitter focuses on the lower less accessible area. The 40 mile float takes 6 days and 5 nights, the only boats that fish this part of the river all season!

Resident and Migratory fish can be caught up and down the river, but the real reason to fish the Limay is the Migratory Browns and Rainbows, which go to huge proportions. Browns average between 26 and 30 inches and trophies ranging from 36 – 40 inches! The Rainbows average 24 to 28 inches with trophies topping 30 inches.

If you want a trophy fish on a fly, and do not want to go to Tierra Del Fiego, the Limay is the trip for you.






A great afternoon walk and wade, lodging is at the picturesque Casa De Campo. At 80 miles this is one of the longest rivers in Northern Patagonia. With the majority of it’s length being very productive trout waters. Which translates into countless fly fishing opportunities. The Aluminé is a freestone river who’s headwaters are Aluminé Lake it then flows to join the Catan-Lil and Chimehuin to become the Collon Cura River. With moderate to no access the fishing pressure is very low. Multi-day or single day floats available. January and February are prime times as the inchworm hatch will be in full force, a great time to hook a big wily Brown Trout.

MALLEO – One of the most famous rivers in Patagonia. Known for it’s excellent dry fly fishing. A mid-size river that flows out of Tromen Lake and is a tributary of the Alumine River. Has what many consider the most abundant and predictable hatches though the fishing season. A medium size river the Malleo is one of the most famous rivers in Patagonia, it’s a dry fly enthusiasts dream. Meandering through steep canyons, large meadows, and willow lined banks. The road following the Malleo allows for easy to moderate access. It is not large enough to float so it is a wade fishing river, while you may encounter a few fly anglers on the river. It is never crowded.


The two sections of the Malleo, the upper and lower have a different feel. The upper section consists of faster moving water and is lined heavily with willows. The lowers section which flows through the Mapuche Indian Reservatio, is slower and becomes more canyon like. Willows only grow at one bank at a time so the lower section is easier to move, cast, and wade through.



Home to one of the largest populations of trout in the entire region. The Chimehuin is one of the most well known fly fishing trout rivers in the world! A classic stream that flows freely through a perfect place for a multi-day float. It would take a lifetime to learn all the holes, riffles and runs. The Lake Huechulafquen formed at the bottom of the Lanín Volcano. It flows for 30 miles until it feeds into the Alumine to form the Collon Cura River. From the town of Junin, to the mouth is known for the best fishing. The lower section is slow and is an amazing dry fly fishery, with very little fishing pressure in the lower section.



One of the largest river systems in the region and a the abode of some very large trout. The Collon Cura is made from numerous rivers with the main tributaries being the Alumine, Chimehuin, and Catan-Lil Rivers and flows nearly 50 miles to the Piedra del Aguila Reservoir. The Collon Cura is a great dry fly river early in the season, then moves to a very unique minnow fishery in mid to late summer then back to a dry fly fishery as the weather cools in fall. Late January massive numbers of minnows move upstream from the lake to spawn. This is a great multi-day float option, with camping on islands and fishing underutilized by other anglers.



One of the most picturesque streams in all of Patagonia, the Caleufu River forms after the conjunction of the Meliquina and Filo Hua-Hum Rivers. Running through a beautiful canyon, rock formations draw your eye and your cast. It becomes a medium sized river roughly 60 miles from the Collon Cura River. Mostly a floating river, this is a wonderful option for your multi-day float, expect to see Andean Condors, and other wildlife as you chase the denizens of the river. The river is floatable up to late January. After that the operation switches to the lower portions to focus on the minnow migration, much like the Collon Cura River.

QUILLEN RIVER - The Quillen River, a tributary of the upper Aluminé is a great dry fly stream, and forms from Quillen Lake in the historic Lanín National Park. A freestone stream flowing for about 16 miles until its junction with the Alumine River. The upper sections run slowly and winds through a beautiful valley, as you move down the river the gradient becomes steeper and forms the classic pocket water many fly fishers treasure. A very small stream the Quillen is only fished by a handful of wade fishermen every year.


Spring Creeks

springcreeks 8563

In addition to the major rivers in the surrounding area we also have fishing access to several spring creeks. These free flowing streams are created by underground aquifers as opposed to melting snow pack from the Andes Mountains. Water is “pushed” by the force of pressure from the underground source and this creates flows that remain relatively consistent and cool throughout the season.

Many of the spring creeks that we fish offer slower moving or flat water. This environment fosters a high degree of insect activity including mayflies and caddis. Not surprisingly, trout (brook, rainbow and brown) thrive in these conditions. This is truly a dry fly fishing paradise for anglers in search of sight fishing and trout hunting possibilities.



Flat out world class guides. We have numerous references. Guides will spend the entire float with you, and are ever present in camp to help mend equipment or just tell stories.

Small Boutique Hotels

We have an established history and working relationship with several boutique hotels in San Martin de los Andes. To meet our selection criteria these hotels must offer high quality accommodations and service.


All international flights leave the US in the evening, usually somewhere between 8pm and 10pm, and arrive in Buenos Aires the following morning. Delta, United and American offer daily flights, as do Aerolineas Argentinas and LAN Airlines. For everyone traveling out of the Southeast, we have found that Delta out of Atlanta or LAN out of Miami offer the best flights. These flights usually cost between $750 and $1,100 round trip. (Please check LAN flights carefully to confirm that you are not flying first into Santiago, Chile, and then on to Buenos Aires.)

Plan for about four hours on the ground between flights once you reach Buenos Aires. You will have to clear Argentina customs and travel to the domestic airport via taxi or shuttle bus. This trip can take anywhere from 30 minutes to an hour and a half, depending on traffic. We will set up this transfer for you, but you will need to pay for it. This usually costs around 300 Argentine pesos (about $100 US) for a group of six.

(Note: Argentina uses the $ symbol to denote its currency, but it represents pesos there, not dollars.)

Your domestic air travel in Argentina is limited to Aerolineas or LAN. Aerolineas is the only airline flying into the San Martin de los Andes area. This is the most convenient option as you land about 15 miles from San Martin de los Andes. However, space is limited and you will need to make your reservations in advance. For alternatives, both LAN and Aerolineas have multiple daily flights to Bariloche, but the drive from there to San Martin de los Andes is approximately three hours.


Electricity in Argentina is 220-volt AC, so you will need an adapter for your computer, cell phone charger, and any other electric appliances you bring from the US. You can purchase a converter at Best Buy or similar stores for about $20.


San Martin de los Andes is a wonderful place for spouses and traveling companions who seek alternatives to fishing, especially those who enjoy a variety of outdoor activities. See our list of activities for non-fishing companions [link to list].



San Martin de los Andes and Bariloche both offer wonderful shopping. Although these are small towns without malls and high-end boutiques like those in Buenos Aires, you will find distinctive stores that sell merchandise ranging from handmade sweaters and leather products to one-of-a-kind items crafted by master silversmiths and local artisans. What’s more, this area is world-renowned for its chocolates. It’s a good idea to buy extra, because many of these delicacies will be eaten before you can take them home!



Should you experience a medical problem during your visit, Argentina has excellent, modern medical facilities and well-trained health care professionals. However, most US insurance companies do not provide coverage in Argentina, and you will have to pay for your treatment on the spot unless you have taken out supplemental medical insurance.
